Description
Summary:The structure of Bi2CdO2[GeO4] was solvedab initioon the basis of laboratory and synchrotron X-ray powder data. The high temperature orthorhombic phase, stable at room temperature, crystallizes inPbcn(60),Z= 8,a= 10.4969(1) Å,b= 10.0944(1) Å,c= 5.60601(3) Å, andV= 594.01(1)Å3with 14 refinable positional parameters. The structure consists of [GeO4] tetrahedra, strongly distorted trigonal [CdO6] prisms and irregular [BiO4+2] polyhedra. At low temperatures, the material undergoes a small distortion to monoclinic symmetry (γ = 90.37° at 20 K).
